Upto v1.44 it was not possible for the user to set their own filters. From v1.45 though that has -all changed. It is now possible to set filters for just about anything you wish. If you have just -updated from an older version of DXSpider you will need to update your new filters. You do not -need to do anything with your old filters, they will be renamed as you update. +
One of the more important things a cluster sysop needs to do is to get +information to his users. The simplest way to do this is to have a banner +that is sent to the user on login. This is know as a "message of the day" +or "motd". To set this up, simply create a file in /spider/data called motd +and edit it to say whatever you want. It is purely a text file and will be +sent automatically to anyone logging in to the cluster.
-
There are 3 basic commands involved in setting and manipulating filters. These are accept, -reject and clear. First we will look generally at filtering. There are a number -of things you can filter in the DXSpider system. They all use the same general mechanism. +
If for any reason the cluster is down, maybe for upgrade or maintenance but +the machine is still running, a message can be sent to the user advising them +of the fact. This message lives in the /spider/data directory and is called +"offline". Simply create the file and edit it to say whatever you wish. +This file will be sent to a user attempting to log into the cluster when +DXSpider is not actually running.
-
In general terms you can create a 'reject' or an 'accept' filter which can have up to 10 lines in -it. You do this using, for example ... +
You can set other text messages to be read by the user if they input the file +name. This could be for news items or maybe information for new users. +To set this up, make a directory under /spider called packclus. +Under this directory you can create files called news or newuser +for example. In fact you can create files with any names you like. These can +be listed by the user with the command ....
-
-accept/spots .....
-reject/spots .....
+show/files
where ..... are the specific commands for that type of filter. There are filters for spots, wwv, -announce, wcy and (for sysops) connects. See each different accept or reject command reference -for more details. -
There is also a command to clear out one or more lines in a filter. They are ... +
They can be read by the user by typing the command ....
-clear/spots 1
-clear/spots all
+type news
There is clear/xxxx command for each type of filter. +
If the file they want to read is called news. You could also set +an alias for this in the Alias file to allow them just to type news
-
and you can check that your filters have worked by the command ... +
You can also store other information in this directory, either directly or +nested under directories. One use for this would be to store DX bulletins +such as the OPDX bulletins. These can be listed and read by the user. +To keep things tidy, make a directory under /spider/packclus called +bulletin. Now copy any OPDX or similar bulletins into it. These +can be listed by the user in the same way as above using the show/files +command with an extension for the bulletin directory you have just created, +like this ....
-
-show/filter
+show/files bulletin
-
For now we are going to use spots for the examples, but you can apply the same principles -to all types of filter. -
-
There are two main types of filter, accept or reject. You can use either -to achieve the result you want dependent on your own preference and which is more simple to -do. It is pointless writing 8 lines of reject filters when 1 accept filter would do the -same thing! Each filter has 10 lines (of any length) which are tried in order. If a line -matches then the action you have specified is taken (ie reject means ignore it and accept -means take it) -
-
If you specify reject filters, then any lines that arrive that match the filter will be -dumped but all else will be accepted. If you use an accept filter, then ONLY the lines -in the filter will be accepted and all else will be dumped. -For example if you have a single line accept filter ... +
An example would look like this ....
-accept/spots on vhf and (by_zone 14,15,16 or call_zone 14,15,16)
+sh/files
+bulletin DIR 20-Dec-1999 1715Z news 1602 14-Dec-1999 1330Z
then you will ONLY get VHF spots from or to CQ zones 14, 15 and 16. -
-
If you set a reject filter like this ... +
You can see that in the files area (basically the packclus directory) there is a +file called news and a directory called bulletin. You can +also see that dates they were created. In the case of the file news, +you can also see the time it was last modified, a good clue as to whether the +file has been updated since you last read it. To read the file called +news you would simply issue the command ....
-reject/spots on hf/cw
+type news
Then you will get everything EXCEPT HF CW spots. You could make this single filter -even more flexible. For example, if you are interested in IOTA and will work it even on CW -even though normally you are not interested in CW, then you could say ... +
To look what is in the bulletin directory you issue the command ....
-reject/spots on hf/cw and not info iota

which achieves exactly the same thing. You should choose one or the other until you are -comfortable with the way it works. You can mix them if you wish (actually you can have an accept -AND a reject on the same line) but don't attempt this until you are sure you know what you -are doing! +
The page length will of course depend on what you have it set to!

You can arrange your filter lines into logical units, either for your own understanding or simply -convenience. Here is an example ... +
You will find a file in /spider/cmd/ called Aliases. First, copy this file to +/spider/local_cmd/Aliases and edit this file. You will see something like this ...

What this does is to ignore all HF CW spots and also rejects any spots on VHF which don't -either originate or spot someone in Europe. +
You can create aliases for commands at will. Beware though, these may not +always turn out as you think. Care is needed and you need to test the +results once you have set an alias.
-
This is an example where you would use a line number (1 and 2 in this case), if you leave the -digit out, the system assumes '1'. Digits '0'-'9' are available. This make it easier to see -just what filters you have set. It also makes it more simple to remove individual filters, -during a contest for example. +
In later versions of Spider a simple console program is provided for the sysop. +This has a type ahead buffer with line editing facilities and colour for spots, +announces etc. To use this program, simply use console.pl instead of client.
-
You will notice in the above example that the second line has brackets. Look at the line -logically. You can see there are 2 separate sections to it. We are saying reject spots that -are VHF or above APART from those in zones 14, 15 and 16 (either spotted there or -originated there). If you did not have the brackets to separate the 2 sections, then Spider -would read it logically from the front and see a different expression entirely ... +
To edit the colours, copy /spider/perl/Console.pl to /spider/local and edit the +file with your favourite editor.
-
-
-(on 50000/1400000 and by_zone 14,15,16) or call_zone 14,15,16
-
-The simple way to remember this is, if you use OR - use brackets. Whilst we are here CASE is not -important. 'And BY_Zone' is just the same as 'and by_zone'. -
As mentioned earlier, setting several filters can be more flexible than simply setting one complex -one. Doing it in this way means that if you want to alter your filter you can just redefine or -remove one or more lines of it or one line. For example ... +
Spider has a powerful and flexible show/satellite command. In order for +this to be accurate, the kepler data has to be updated regularly. In +general, this data is available as an email or via cluster mail. +Updating it is simple. First you need to export the mail message as a +file. You do this with the export command from the cluster prompt +as the sysop. For example ...
-reject/spots 1 on hf/ssb
+export 5467 /spider/perl/keps.in
would redefine our earlier example, or +
would export message number 5467 as a file called keps.in in the +/spider/perl directory. +
Now login to a VT as sysop and cd /spider/perl. There is a command in +the perl directory called convkeps.pl. All we need to do now is +convert the file like so ...
-clear/spots 1
+./convkeps.pl keps.in
To remove all the filter lines in the spot filter ... +
Now go back to the cluster and issue the command ...
-clear/spots all
+load/keps
That is it! the kepler data has been updated.
-
Once you are happy with the results you get, you may like to experiment. -
-
The previous example that filters hf/cw spots and accepts vhf/uhf spots from EU -can be written with a mixed filter, for example ... -
-
-
-rej/spot on hf/cw
-acc/spot on 0/30000
-acc/spot 2 on 50000/1400000 and (by_zone 14,15,16 or call_zone 14,15,16)
-
-Note that the first filter has not been specified with a number. This will -automatically be assumed to be number 1. In this case, we have said "reject all -HF spots in the CW section of the bands but accept all others at HF. Also -accept anything in VHF and above spotted in or by operators in the zones -14, 15 and 16". Each filter slot actually has a 'reject' slot and -an 'accept' slot. The reject slot is executed BEFORE the accept slot. -
-
It was mentioned earlier that after a reject test that doesn't match, the default -for following tests is 'accept', the reverse is true for 'accept'. In the example -what happens is that the reject is executed first, any non hf/cw spot is passed -to the accept line, which lets through everything else on HF. The next filter line -lets through just VHF/UHF spots from EU. -
+
The command sh/qrz will only work once you have followed a few +simple steps. First you need to get a user ID and password from qrz.com. +Simply go to the site and create one. Secondly you need to copy the file +/spider/perl/Internet.pm to /spider/local and alter it to match your user +ID and password. You also at this point need to set $allow=1 to complete +the setup. Many thanks to Fred Lloyd, the proprieter of +qrz.com for allowing this access.
